What this research seeks is to know what happens in the researcher’s life when he/she investigates, in other words, what is the researcher’s world-of-life (Lebenswelt), how to establish a balance between the world-of-the-life of the researcher and the research itself, in all areas of knowledge, such as theology and religious sciences. The question that guides this research is: what is the life experience of the researcher like during the research process itself and how can research influence the researcher’s “life-world” (lebenswelt)? What this research intends is to make the researcher the very object of research. In the phenomenology of Husserl, and of other phenomenologists, methodological and theoretical resources were found with the consistency and rigor necessary to carry out a descriptive analysis of the construction of the daily “world-of-life” in the experience of researchers. From a Systematic Review of Literature, the research problem could be constructed, based on the consultation of scientific databases (Scopus and ATLA), In addition, the in-depth interview technique was used, which allowed working on 9 stories of life. Finally, there is a need to train researchers not only in the technical and instrumental aspects of research, but also in those other matters that touch the world-of-life of the researcher looking for a “quality of life”, which is the wish of all areas of scientific research, and not only of theology and the sciences of religion.
